Title: Anisotropic magnetic behaviors of monoclinic Li{sub 3}Fe{sub 2}(PO{sub 4}){sub 3}

Large sized α-Li{sub 3}Fe{sub 2}(PO{sub 4}){sub 3} single crystals with high quality are successfully grown by a flux method. Magnetic behaviors of the grown crystals are investigated by means of magnetic susceptibility, magnetization, and heat capacity measurements along different directions. The results confirm that α-Li{sub 3}Fe{sub 2}(PO{sub 4}){sub 3} exhibits weak ferrimagnetic behaviors at low temperature, which are in good agreement with those reported previously. However magnetic anisotropy is confirmed for the first time, suggesting that the c-axis is the likely magnetic easy axis and the a-axis is the magnetic hard one. Two anomalies are clearly observed in magnetic susceptibility along the a-axis and heat capacity data at zero field, suggesting the appearance of two successive magnetic transitions at ∼26 and ∼22 K in the system. - Graphical abstract: Magnetic anisotropy is confirmed for the first time using a single crystal sample of α-Li{sub 3}Fe{sub 2}(PO{sub 4}){sub 3} obtained by the flux method. - Highlights: • Large-sized single crystals of α-Li{sub 3}Fe{sub 2}(PO{sub 4}){sub 3} are grown by the flux method. • Magnetic anisotropy is confirmed for the first time in the system. • Two successive magnetic transitions are observed along the a-axis.
